Abstract
There is disclosed a technique for providing a global connectivity to a mobile node connected to a mobile access router forming a mobile network via a local fixed router. According to the technique, the mobile node (1000-1) can acquire a global address of the access router (mobile access router 1200-1) connected via the local fixed router (1100-1). For example, by using the mobile node, transmission of a biding update message having a special mark embedded and transmission of a special packet are performed. The mobile access router which receives the message and the packet transmitted from the mobile node recognizes that the mobile node doesnot know the primary global address of the mobile access router and reports its own primary global address to the mobile node.
Description
Technical field
The present invention relates to provide overall internuncial communication network technology.
Background technology
At present, the internet has been developed to the stage of disposing numerous external data communication networks around fixed network node system.These data communication networks are correspondingly called edge network, simultaneously edge network around fixed network node system call core network.Along with the appearance and the development of wireless technology, more and more such edge networks are using wireless solution, thereby have formed a kind of mobile network of being called, or the particular edge network (referring to following non-patent literature 1) of the network in moving.
In fact, the mobile network is the knot-net that a kind of wherein whole network constantly changes the attachment point of itself and internet.This usually need be in the mobile router among the mobile network of the attachment point that constantly changes itself and internet between the different access routers (in fact, they itself also are movably) (its mobile network and internet bridge joint) in addition.Mobile network's example comprises the network (being called personal area network, i.e. PAN) that attaches to the people and is deployed in network such as the transducer in the delivery vehicle of automobile, train, steamer or aircraft.For large-scale transportation system such as aircraft, train or bus, the access to the Internet that operating personnel may be when the passenger provides the persistence that allows the passenger to use their laptop, personal digital assistant (PDA) or mobile phone to link to each other with distance host to take.Usually, the individual node among such mobile network is connected to a central apparatus (being mobile router), and does not change the attached of them when network moves.Replace, when network integral body was mobile, mobile router changed its attachment point.
In fact, the problem of the network in moving is that the node in the network that integral body moves provides continuous internet connectivity.Node in the network that moves may not know that network is changing the attachment point of itself and internet.This is different from Mobile IPv4 (referring to following non-patent literature 2) in the 4th edition (IPv4) (referring to following non-patent literature 3) of Internet Protocol and the related traditional mobility support issue of Mobile IPv6 (referring to following non-patent literature 4) in the 6th edition (Ipv6) (referring to following non-patent literature 5) of Internet Protocol.In non-patent literature 2 and 4, main purpose is to individual hosts, rather than provides the mobility support to whole network.
In Mobile IP, each mobile node has territory, persistence local (home domain).When the mobile network was attached to its home network, it had been endowed the main global address that is called home address.When the mobile network leaves, promptly when it being attached to other other places (foreign) network, give the interim global address that is called Care-of Address (care-of-address) to it usually.The notion of mobility support is, or even when mobile node is attached to other field network, also can arrives mobile node according to home address.Realized this point by the entity of having introduced the home network place that is called home agent in the non-patent literature 2 and 4.Mobile node uses the message that is called Binding Update (Bingding Update), to their Care-of Address of home agent registration.Home agent is responsible for tackling the message of the home address of mobile node being carried out addressing, and uses IP-in-IP (IP among the IP) tunnel (Tunnelling) (referring to following non-patent literature 6 and 7) to forward the packet to the Care-of Address of mobile node.The IP-in-IP tunnel relates to an initial IP packet encapsulation in another IP grouping.Sometimes, original packet is called inner grouping, the new grouping of the inner grouping of encapsulation is called external packet.
Since the conceptual expansion of supporting at the mobility of individual hosts to mobility support at knot-net, so the purpose of network plan provides a kind of like this mechanism in moving: wherein, can arrive this node according to the main global address of the node among the mobile network, and no matter where the mobile network be attached to go the internet.Exist some to solve the trial of the problem of the network in moving, they all are based on Mobile (moving) IP (referring to non-patent literature 3 and 4).
Provided a kind of proposal scheme that is used for mobile network in the following patent documentation 1.Herein, when control mobile network's mobile router when being in its territory, local, it uses some Routing Protocol to carry out to the mobile network with from the route of mobile network's grouping.When mobile router and mobile network thereof moved to outside one the region, mobile router was registered its Care-of Address to its home agent.Then, between mobile router and home agent, set up the IP-in-IP tunnel.Also carrying out employed Routing Protocol when mobile router is in its territory, local on the IP-in-IP tunnel.This means that home agent goes to each grouping of mobile network with interception, and they are forwarded to mobile router by the IP-in-IP tunnel.Mobile router forwards a packet to the main frame among its mobile network then.When a node among its mobile network wished to be sent in grouping outside the network, mobile router was tackled this grouping, and will forward a packet to home agent to this by the IP-in-IP tunnel.Home agent is issued to the recipient who is intended to this grouping then.
Disclosed another kind of scheme is similar substantially except it states support to IPv6 (referring to non-patent literature 5) especially in the following patent documentation 2.
Known various wireless technology (being bluetooth, IEEE 802.11a/b/g, ultra broadband, infrared, General Packet Radio Services), be not difficult to imagine such a case: wherein, exist nested mobile network, promptly a mobile network is among another mobile network.Use the scheme of being advised in the patent documentation 1, this has caused the problem that is called reciprocal route (ping-pong routing) or nested tunnel.Nested tunnel is such a case: wherein, the tunnel that a mobile router and its home agent are set up is encapsulated in another tunnel that another mobile router and its home agent set up.The nested of tunnel will cause the increase of elapsed time of dividing into groups, and arrive at before its final destination because be grouped in, and need the more than one home agent of visit.In addition, a plurality of encapsulation have also increased the size of grouping, thereby have caused unnecessary partization (fragmentation).
In order to address this problem, the another kind of scheme of being advised in the following non-patent literature 8 relates to the use to anti-route header (Reverse Routing Header), has too many encapsulated layer when mobile network nested (promptly a mobile network oneself attaches to another mobile network to it) so that avoid.Herein, the lowermost layer mobile network is setting up an anti-route header in its tunnel packet of its home agent.When high-rise mobile router in its way when intercepting this grouping, this more high-rise mobile router not this packet encapsulation in another IP-in-IP tunnel.Replace, this high level mobile router is copied to the source address in this grouping in the anti-route header, and its oneself Care-of Address is changed to source address.Under this mode, when the home agent of first mobile router received this grouping, it can determine to be in the mobile router chain in first mobile router and the path between itself.Next, when this home agent wishes to transmit another grouping of tackling at first mobile router, it can comprise 2 type route headers of an expansion, so that can directly be sent to first mobile router to this grouping via other high-rise mobile router.
Safety is a subject matter of the anti-route header scheme in the non-patent literature 8.Following non-patent literature 9 has been advised a kind of comparatively safe scheme at nested tunnel optimization problem.This scheme, (Access Router Option, ARO) scheme have defined a new option in the mobility leader of defined in Mobile IPv6 to be called the access router option.This new option is called the access router option, and the side of being sent out (being mobile router or mobile host) uses, the main global address of the access router that transmit leg was attached to is notified the recipient (for example home agent or the other side's node).Sent after the binding update messages with access router option, next, mobile node can be inserted into the packet that it sends to a distinctive signal that calls " directly transmitting request (direct-forwarding-request) " signal.This signal will cause upstream mobile access router that its oneself Binding Update is sent in destination-address.Repeat this process, until arriving at top layer mobile access router.Send Binding Update by all upstream mobile access routers to the destination, this destination can build mobile node the chain of attached mobile access router.This can be used for constructing 2 type route headers of expansion, therefore, wishes that when the destination node when mobile node was beamed back a grouping, it can embed route header to this grouping, and this grouping will be routed directly to mobile node via mobile access router chain.

Transmit leg knows that the mode of the main global address of its access router is the advertisement information of broadcasting by access router.Stipulated router advertisement in the non-patent literature 10.In non-patent literature 9, support the access router of this scheme must be on one's own initiative to be issued to its main global address of its outlet of broadcasting (egress interface) in the router advertisement of its inlet (ingress) at it.Below, the information in the router advertisement that contains main global address is called " access router address information (Access-Router-Address-Information) " or abbreviate " ARA-Info " as.So, the mobile node that is attached to the inlet of access router will be known the main global address of access router, and find access router support ARO scheme.
When having the local router of intervention between medial movement node and outside mobile router, this is provided with existing problems.Among Fig. 1 this is illustrated.In Fig. 1, mobile node 1000-1 attaches to localized immobilization router one 100-1.Be connected to localized immobilization router one 100-1 persistence mobile access router one 200-1.Usually can see this deployment mode in the large-scale traffic carrier such as train or steamer, wherein, the mobile access router is used to provide the visit of train/steamer to overall internet.The localized immobilization router that is connected to the mobile access router is deployed in each compartment/cabin of train/steamer, to provide wireless connections to each compartment/cabin.As the laptop of mobile host (or the PDA among the wireless PAN, as mobile router), can attach to one of these localized immobilization routers at wireless PAN.
A kind of deployment mode has like this formed the localized immobilization router and has resided in situation between mobile node and the mobile access router.Owing to be connected to mobile access router one 200-1 to localized immobilization router one 100-1 persistence, so it does not need to have or understand mobility protocol.It is simply to going to and carrying out route from the grouping of mobile node 1000-1 and mobile access router one 200-1.Therefore, the localized immobilization router will not use the agreement relevant with mobility, this means that router advertisement that localized immobilization router one 100-1 is sent will not comprise its oneself main global address.
This configuration of network design will cause the failure of ARO scheme, because the router advertisement that localized immobilization router one 100-1 is broadcasted will not comprise any ARA-Info.In addition, even the router advertisement that mobile access router one 200-1 is sent will be contained in its own main global address among the ARA-Info, mobile node 1000-1 also can not receive such advertisement.This is because only can jump transmission router advertisement in (hop) one, and not forwarding router advertisements of all-router of pressing the IPv6 protocol operation.
A kind of conspicuous scheme is that the localized immobilization router that makes all be deployed among the mobile network is supported the ARO scheme.Yet, do like this and have its defective.At first, this means the compatibility that has lost with traditional router.Secondly, by on the router that does not change its attachment point, supporting a whole set of ARO scheme (this is a kind of mobility protocol), unnecessarily increased the complexity of system.This is converted into higher development cost and the maintenance cost of Geng Gao.
Summary of the invention
The present invention has strengthened the ARO scheme by 4 kinds of diverse ways of regulation among the embodiment that comprises at each.First method is that mobile node 1000-1 embeds special marking in the binding update messages that it sends.Mobile access router one 200-1 will scan such signal, thereby know and send the Founder mobile access router that tries to find out.Mobile access router one 200-1 tells transmit leg its main global address then.
Second method is that mobile access router one 200-1 thoroughly scans the grouping that all enter, to seek the binding update messages that mobile node 1000-1 is sent.Because mobile node 1000-1 is using the ARO scheme, so in binding update messages, be provided with particular bit.Mobile access router one 200-1 will know that transmit leg is supported the ARO scheme, but not know the main global address of its access router.Mobile access router one 200-1 tells transmit leg its main global address then.
The third method is, mobile node 1000-1 is sent in all-router in its upstream to particular packet.When receiving this grouping, the router of support ARO scheme will be answered the main global address with them.
Last a kind of method is to dispose localized immobilization router one 100-1, so that its ARA-info that will have the main global address of its mobile access router that is connected to is embedded in the router advertisement message of localized immobilization router one 100-1 self transmission.
The invention enables,, also can provide overall connectivity to mobile node and mobile network even the localized immobilization router resides in the mobile access router that forms the mobile network and is connected between this mobile network's the mobile node.

In the following description, for the ease of explaining, concrete numeral, time, structure and other parameter have been provided, to provide to overall understanding of the present invention.Yet, any technical staff in this area be will be apparent from, can under the situation of not using these details, put into practice the present invention.
＜the first embodiment 〉
The first embodiment of the present invention has been described such a case: when a mobile node sends binding update messages, use a special marking that is embedded in the packet header.When detecting such special marking, upstream mobile access router will be its HoA notice mobile node.
Fig. 1 has illustrated the system that wherein can dispose mobile node of the present invention and global data communication network.Mobile node 1000-1 is attached to localized immobilization router one 100-1.Localized immobilization router one 100-1 itself is attached to mobile access router one 200-1.Note, for simplicity, only described a localized immobilization router one 100-1 who attaches to mobile access router one 200-1, and only described a mobile node 1000-1 who attaches to localized immobilization router one 100-1.In the deployment of reality, may there be the localized immobilization router one 100-1 of the arbitrary number that attaches to mobile access router one 200-1, and the mobile node 1000-1 that attaches to one of any arbitrary number of these localized immobilization router ones 100-1.Should be very clear to any technical staff in this area, the present invention also will be suitable for such situation.
And, be mobile host or mobile router about mobile node 1000-1, do not provide any regulation.In fact, itself also can be mobile access router one 200-1.Specially use to term " mobile node " is intended to be without loss of generality.Mobile host both represented in term " mobile node ", also represents mobile router.Any technical staff in this area also should be clear, and the situation when the present invention both had been suitable for mobile node 1000-1 and is mobile host also is suitable for the situation of mobile node 1000-1 when moving (visit) router.
In addition, although a localized immobilization router one 100-1 has been shown in the path between mobile node 1000-1 and mobile access router one 200-1, in fact may there be a plurality of such localized immobilization router one 100-1 between mobile node 1000-1 and mobile access router one 200-1 connected in series.Any technical staff in this area it will be appreciated that the present invention is equally applicable to use the situation that one or more localized immobilization router one 100-1 is arranged between mobile node 1000-1 and the mobile access router one 200-1.
Mobile access router one 200-1 is attached to global data communication network 1600-1.This network 1600-1 can be any packet switching network, perhaps is actually internet itself.That attach to global data communication network 1600-1 is home agent 1400-1 and 1400-2, and they are used separately as the home agent of mobile node 1000-1 and mobile access router one 200-1.Attach to persistence the localized immobilization router one 100-1 of mobile access router one 200-1, do not have mobility protocol, thereby do not need home agent.The other side's node 1500-1 is any node (perhaps mobile node 1000-1 is under the situation of mobile access router therein, is any mobile node after mobile node 1000-1) on the global data communication network 1600-1 that has with the ongoing service conversation of mobile node 1000-1.
When mobile node 1000-1 started first, it was from localized immobilization router one 100-1 receiving router advertisement information.Then, mobile node 1000-1 disposes the CoA of himself according to the prefix information that is carried in the router advertisement.Next, the mobile node 1000-1 new CoA that need will be bound to its HoA by sending BU message to home agent 1400-1 and the other side's node 1500-1 notifies them.Because the router advertisement that localized immobilization router one 100-1 is sent does not comprise any ARA-Info, so mobile node 1000-1 can not comprise any access router option in the BU message that it sends.Replace, mobile node 1000-1 embeds special marking in the packet header of BU message, should answer HoA with them to indicate follow-up upstream mobile access router.In order to be easy to explain, below such mark to be called " access router Address requests (Access-Router-Address-Request) " signal, or be abbreviated as " ARA-Req ".ARA-Req can be the form of specific bit or bit stream.For example, in IPv6, exist hop-by-hop (hop-by-hop) option (referring to non-patent literature 11) that is called router alert option.This special marking can be taked the form of the particular value in the router alert option.
Localized immobilization router one 100-1 receives grouping, and after confirming to be grouped into effectively, transmit in mobile access router one 200-1 its grouping upstream.Mobile access router one 200-1 will check the grouping that enters from its one or more inlet at the signal of any embedding ARA-Req for example.When detecting ARA-Req, except to the normal process that enters grouping, mobile access router one 200-1 also needs to take specific action.At first, mobile access router one 200-1 will construct a new grouping, with its HoA notice mobile node 1000-1 (as have in the source address field that enters grouping of ARA-Req signal appointment).Following this grouping is called " (Access-Router-Address-Response) answered in the access router address " signal, or be abbreviated as " ARA-Res ".Secondly, the grouping that enters that mobile access router one 200-1 will remove or mark has the ARA-Req signal again will not be so that follow-up upstream router will be answered ARA-Req.Under this mode, following situation is possible, and the first mobile access router one 200-1 that only detects the ARA-Req signal in the grouping will be sent in mobile node 1000-1 to ARA-Res.Following situation also is possible, when mobile access router one 200-1 upstream transmit have the ARA-Req signal enter grouping the time, if another mobile access router one 200-1 resides in further upstream end, then this upstream mobile access router one 200-1 also will be sent in mobile node 1000-1 to ARA-Res.
The ARA-Res grouping that mobile access router one 200-1 is sent in mobile node 1000-1 is loaded with following message with needs: (1) is indication to the answer of ARA-Req about this grouping, and (2) specify the value of the HoA of mobile access router one 200-1.Alternatively, the ARA-Res grouping also can be loaded with the part of original packet (grouping with ARA-Req), so that mobile node 1000-1 can verify that this is effective answer.
In order to remove ARA-Req, definite method depends on how ARA-Req realizes.If ARA-Req is the bit in the packet header, then mobile access router one 200-1 can remove this bit simply to remove ARA-Req.If ARA-Req is realized as the value in the router alert option, then mobile access router one 200-1 can abandon router alert option simply to remove ARA-Req, or this value changed over a certain other value, so that follow-up router will be ignored router alert option simply.
When ARA-Res when grouping that receives the HoA that contains mobile access router one 200-1, then mobile node 1000-1 then can before come in the to send new BU message of access router option with the HoA that contains mobile access router one 200-1 to its home agent 1400-1 and/or the other side's node 1500-1.At this moment, mobile node 1000-1 should not insert ARA-Req, and should follow the behavior of ARO scheme defined.
Say that briefly when sending BU message, mobile node 1000-1 will follow the algorithm described in Fig. 2.In step S11000, mobile node 1000-1 checks whether it knows the HoA of its access router.If it knows (perhaps ARA-Info by from router advertisement message, extracting, or by the previous ARA-Res message that receives), then mobile node 1000-1 will equal value the access router option insertion BU of the HoA of access router, as shown in step S11100.If it does not know that then mobile node 1000-1 inserts the ARA-Req signal in the packet header of BU message, as shown in step S11200.
For mobile access router one 200-1, the present invention requires its processing is revised slightly from the mode that enters grouping of its inlet.This modification has been described among Fig. 3.At first, in step S12000, mobile access router one 200-1 checks in the grouping whether have the ARA-Req signal.If do not find such signal, then mobile access router one 200-1 turns to step S12300, and wherein it is followed and enters packet transaction normally.If grouping comprises ARA-Req, then it will turn to step 12100 and step S12200 before turning to step S12300.In step 12100, mobile access router one 200-1 divides into groups an ARA-Res who comprises its HoA to send to enter source address specified in the grouping.In step S12200, it removes ARA-Req message from enter grouping, and in step S12300, it carries out the processing that enters grouping normally.
Notice that when storing the HoA of mobile access router one 200-1, mobile node 1000-1 should be stored this HoA with the information of its current default router (being localized immobilization router 0000-1).Do like this when moving to a new position with convenient mobile node 1000-1, the variation of its default router will cause it also to remove the HoA of the mobile access router one 200-1 that is stored.
Therefore, use the first embodiment of the present invention, or even exist under the situation of other router between mobile node and the mobile access router, mobile node also has the mechanism of the HoA of knowing upstream mobile access router.This allows mobile node that the access router option is embedded binding update messages, thereby allows the normal operation of ARO scheme.
＜the second embodiment 〉
The second embodiment of the present invention has been described such a case: mobile access router one 200-1 thoroughly scans all groupings that enter by its one or more inlet, to seek the binding update messages that mobile node 1000-1 is sent.Because mobile node 1000-1 is using the ARO scheme, so be provided with specific bit in binding update messages.Mobile access router one 200-1 will know that transmit leg supports the ARO scheme but do not know the HoA of its access router.So the mobile access router one 200-1 tell transmit leg its HoA.
For this second embodiment, reused the deployment mode among Fig. 1.When mobile node 1000-1 started first, it was from localized immobilization router one 100-1 receiving router advertisement information.Mobile node 1000-1 disposes the CoA of himself then according to the prefix information that is loaded with in the router advertisement.Next, the mobile node 1000-1 new CoA that need will be bound to its HoA by sending BU message to home agent 1400-1 and the other side's node 1500-1 notifies them.Because the router advertisement that localized immobilization router one 100-1 is sent does not contain any ARA-Info, so mobile node 1000-1 can not comprise any access router option in the BU message that it sends.
Mobile node 1000-1 can selectively use preassigned value in the access router option (for example complete 0 or 1 address) to indicate: although it is using the ARO scheme, it does not know the HoA of (still not knowing) its access router.Sometimes this may be unnecessary, is using the ARO scheme because the ARO scheme can require mobile node 1000-1 that specific bit is set in BU message to represent it.In view of the above, not existing of access router option is enough to indicate the HoA that mobile node 1000-1 does not know its access router.
Localized immobilization router one 100-1 receives grouping, after confirming grouping effectively, next, the grouping upstream is transmitted in mobile access router one 200-1.Mobile access router one 200-1 will check about whether any is a BU message in these groupings for the grouping that enters in its one or more inlet.When detecting BU message, except the normal process that enters grouping, mobile access router one 200-1 will need further to check whether BU indicates transmit leg using the ARO scheme.
The ARA-Res grouping that mobile access router one 200-1 is sent in mobile node 1000-1 is loaded with following message with needs: (1) is the indication of notifying the message of the HoA of mobile access router one 200-1 about this grouping, and (2) specify the value of the HoA of mobile access router one 200-1.Alternatively, the ARA-Res grouping also can be loaded with the part of (grouping with BU message) of original packet, so that mobile node 1000-1 can verify that this is effective answer.
When ARA-Res when grouping that receives the HoA that contains mobile access router one 200-1, then mobile node 1000-1 can be then can before come in the to send new BU message of access router option with the HoA that contains mobile access router one 200-1 to its home agent 1400-1 and/or the other side's node 1500-1.At this moment, mobile node 1000-1 should take the behavior of ARO scheme defined.
Say that briefly when sending BU message, mobile node 1000-1 will adopt the algorithm described in Fig. 4.In step S21000, mobile node 1000-1 checks whether it knows the HoA of its access router.If it is known (perhaps by the ARA-Info from the router advertisement message extraction, perhaps by the previous ARA-Res message that receives), then mobile node 1000-1 will equal value the access router option insertion BU of the HoA of access router, as shown in step S21100.If it does not know that then mobile node 1000-1 will send BU message, so that the node of this BU message of any inspection all will be recognized: mobile node 1000-1 is using the ARO scheme, but does not know the HoA of its access router, and S21200 is indicated as step.In other words, in step S21200, mobile node 1000-1 sends the information of the use with indication ARO scheme, but does not have the BU of access router option.
For mobile access router one 200-1, the present invention requires its processing is revised slightly from the mode that enters grouping of its inlet.This has been described-revise among Fig. 5.At first, in step S22000, mobile access router one 200-1 checks whether enter grouping is BU message.If it is not, then carry out normal packet transaction, as shown in the step S22300.If entering grouping is BU message, then in step S22100, mobile access router one 200-1 checks further whether BU message is pointed out to send Founder and attempted to use the ARO scheme, but does not know the HoA of its access router.This can be from lacking the access router option and having the bit of indication to the use of ARO scheme, perhaps derives out from the access router option of the address (for example all zeros address, or all ones address) that comprises special marking.
The transmission Founder of BU message attempts to use the ARO scheme if it can not be derived, but do not know the HoA of its access router, then mobile access router one 200-1 turns to step S22300, and in step S22300, what it followed defined in the original ARO scheme enters packet transaction normally.The transmission Founder of BU message attempts to use the ARO scheme if it can be derived, but do not know the HoA of its access router, then mobile access router one 200-1 turns to step S22200, in step S22200, carry out shown in the S22300 enter packet transaction normally before, its source address specified in entering grouping sends the ARA-Res grouping that comprises its HoA.
As among first embodiment, when storing the HoA of mobile access router one 200-1, mobile node 1000-1 should be stored the HoA of mobile access router one 200-1 with the information of its current default router (being localized immobilization router one 100-1).Do like this when moving to a reposition with convenient mobile access router one 200-1, the variation of its default router will cause it also to remove the HoA of the mobile access router one 200-1 that is stored.
Therefore, use the second embodiment of the present invention, or even exist under the situation of other router between mobile node and the mobile access router, mobile node also has the mechanism of the HoA of knowing upstream mobile access router.This allows mobile node that the access router option is embedded binding update messages, thereby allows the normal operation of ARO scheme.
＜the three embodiment 〉
The third embodiment of the present invention has been described such a case: the all-router of mobile node in its upstream sends particular packet.When receiving this grouping, the router of support ARO scheme will be replied the home address with them.
For this 3rd embodiment, reused the deployment mode among Fig. 1.When mobile node 1000-1 started first, it was from localized immobilization router one 100-1 receiving router advertisement information.Mobile node 1000-1 disposes the CoA of himself then according to the prefix information that is loaded with in the router advertisement.Next, the mobile node 1000-1 new CoA that need will be bound to its HoA by sending BU message to home agent 1400-1 and the other side's node 1500-1 notifies them.Because the router advertisement that localized immobilization router one 100-1 is sent does not contain any ARA-Info, so mobile node 1000-1 can not comprise any access router option in the BU message that it sends.
When this thing happens, mobile node 1000-1 postponed the transmission of BU message, replaces, and sends out particular packet to all upstream routers and knows their HoA with request.This particular packet can be the form of Internet Control Message Protocol (ICMP), and wherein to indicate it be the Address requests of access router to a particular type.Perhaps, it also can be normal router solicitation message (referring to non-patent literature 10), and wherein special option indication recipient should be included in their home address in the router advertisement answer.For the ease of explaining, we call the access router address to this grouping and survey (AccessRouter Address Probe) message, or abbreviate ARA-Probe as.
Because mobile node 1000-1 does not know the existence of upstream mobile access router one 200-1, so it must use broadcast or multicast (multicast) address in the destination field of ARA-Probe.IPv6 has defined a kind of " all-router multicast address " that relates to all-router.Mobile node 1000-1 can be this address as destination-address.Perhaps, also can define a kind of special multicast address, so that it only relates to upstream router.Below, this multicast address is called the upstream router multicast address.This means that all-router will silently ignore any grouping that is addressed to the upstream router multicast address that outlet received from them, and will be the outlet that forwards a packet to that is addressed to the upstream router multicast address that is received from inlet.
For general stream (flooding) amount of limiting multicast address, IPv6 has the jumping limited field, is used to limit the number of times that can transmit a grouping.Mobile node 1000-1 can use little jumping limits value (for example 2 or 3) to reduce general stream.
Localized immobilization router one 100-1 will receive ARA-Probe.It will not understand this grouping probably, but will continue this grouping of forwarded upstream (promptly being forwarded to mobile access router one 200-1).In case mobile access router one 200-1 receives this grouping, it will be sent in ARA-Res the transmit leg (being mobile node 1000-1) of this ARA-Probe, described in the first embodiment of the present invention.
Mobile access router one 200-1 is loaded with following message to the ARA-Res grouping that mobile node 1000-1 sends with needs: (1) is indication to the answer of ARA-Probe about this grouping, and the value of the HoA of (2) indication mobile access router one 200-1.Alternatively, the ARA-Res grouping also can be loaded with the part of (grouping with BU message) of original packet, so that mobile node 1000-1 can verify that this is effective answer.Because mobile access router one 200-1 has answered with ARA-Res, so if mobile access router one 200-1 should not continue forwarded upstream ARA-Probe, then its can before come in to abandon to have the grouping of ARA-Probe, perhaps delete ARA-Probe message or make ARA-Probe message invalid, carry out then with at the identical processing of the processing of normal packets.
After mobile node 1000-1 had received ARA-Res, it can send its BU message of having filled in the access router option.Remaining operation of mobile node 1000-1 and mobile access router one 200-1 will be followed the operation of stipulating in the original ARO scheme.Notice that it is possible that mobile node 1000-1 uses broadcasting method to receive more than one ARA-Res.In this case, mobile node 1000-1 should use its initial ARA-Res that receives, and is regarded as nearest because answer the fastest answer side.
The summary speech, when sending BU message, mobile node 1000-1 will adopt the algorithm described in Fig. 6.In step S31000, mobile node 1000-1 checks whether it knows the HoA of its access router.If mobile node 1000-1 knows that this HoA is (perhaps by the ARA-Info from the router advertisement message extraction, perhaps by the previous ARA-Res message that receives), then mobile node 1000-1 will equal value the access router option insertion BU of the HoA of access router, as shown in step S31100.If mobile node 1000-1 does not know this HoA, then mobile node 1000-1 will turn to step S31200, and in step S31200, it sends ARA-Probe.Mobile node 1000-1 enters wait state then, and as shown in step S31300, in step S31300, it is waited for and receives effective ARA-Res, perhaps wait timeout (timeout).When receiving effective ARA-Res, mobile node 1000-1 will turn to step S31100, and in step 31100, the BU of access router option has been inserted in its transmission, wherein, the value of the HoA of access router is set to equal the value of the HoA that extracts from ARA-Res.When its when being overtime, mobile node 1000-1 supposes not have mobile access router one 200-1 in its upstream, and precedingly comes in to send the not BU of any access router option of tool, as shown in step S31400.
For mobile access router one 200-1, the present invention requires its processing is revised slightly from the mode that enters grouping of its inlet.This modification has been described among Fig. 7.At first, in step S32000, mobile access router one 200-1 checks whether enter grouping is ARA-Probe.If grouping is not ARA-Probe, then mobile access router one 200-1 turns to step S32100, and in step S32100, it is followed and enters packet transaction normally.If grouping is ARA-Probe, then mobile access router one 200-1 will turn to step S32200, and in step S32200, its source address specified in entering grouping sends the ARA-Res grouping that comprises its HoA.
As among above mentioned first embodiment, when storing the HoA of mobile access router one 200-1, mobile node 1000-1 should be stored the HoA of mobile access router one 200-1 with the information of its current default router (being localized immobilization router one 100-1).Do like this when moving to a reposition with convenient mobile node 1000-1, the variation of its default router will cause it also to remove the HoA of the mobile access router one 200-1 that is stored.
As the above mentioned, use the third embodiment of the present invention, or even exist under the situation of other router between mobile node and the mobile access router, mobile node also has the mechanism of the HoA of knowing upstream mobile access router.This allows mobile node that the access router option is embedded binding update messages, thereby allows the normal operation of ARO scheme.
＜the four embodiment 〉
The fourth embodiment of the present invention has been described such a case: the localized immobilization router is configured so that it can be embedded into the main global address of the mobile access router that it was connected in the router advertisement message of localized immobilization router transmission itself.
For the 4th embodiment, reused the deployment mode among Fig. 1.Herein, localized immobilization router one 100-1 is configured to monitor its outlet at the router advertisement that its default router (being mobile access router one 200-1) is sent.
Comprise ARA-Info in case detect router advertisement, localized immobilization router one 100-1 will store the address of extracting from ARA-Info.Next, when local fixed router 1100-1 is issued to its oneself router advertisement its one or more inlet, it will insert the ARA-Info of this HoA that comprises its default router in the router advertisement.Therefore, for mobile node 1000-1, will seem that localized immobilization router one 100-1 is a mobile access router of supporting the ARO scheme seemingly; And in fact, localized immobilization router one 100-1 does not need to understand the major part of ARO scheme.Replace, its needs know how to have extracted the HoA of mobile access router one 200-1 there from it from the router advertisement that mobile access router one 200-1 receives, then the HoA of mobile access router one 200-1 is inserted in the router advertisement of localized immobilization router one 100-1 self transmission.
When storing the HoA of mobile access router one 200-1, localized immobilization router one 100-1 should be stored this HoA with the information of its current default router (being mobile access router one 200-1).Do like this when moving to a reposition with convenient mobile node 1000-1, the variation of its default router will cause it also to remove the HoA of the mobile access router one 200-1 that is stored.
Therefore, in the fourth embodiment of the present invention, be localized immobilization router one 100-1 for unique modification of original ARO scheme.Mobile node 1000-1 and mobile access router one 200-1 all follow the process of defined in the original ARO scheme.Fig. 8 has described the modification from the normal process that enters grouping of the outlet of localized immobilization router one 100-1.In step S41000, localized immobilization router one 100-1 checks at first whether the grouping that enters from outlet is router advertisement.If enter grouping is not router advertisement, and then execution in step S41100 in step S41100, will carry out the normal process (at may handling of all general ip routers) of grouping.If entering grouping is router advertisement, then will carry out normal process, as shown in step S41200 to router advertisement.This process can cause localized immobilization router one 100-1 to change the default router that it disposes.
In this processing (processing of step S41200) afterwards, check router advertisement, to check that it is whether from the default router of localized immobilization router one 100-1, as shown in step S41300.If it is not from default router, then do not require further processing.If it is from default router, then next in step S41400, check router advertisement, check whether it comprises ARA-Info.If router advertisement does not comprise ARA-Info, then remove the built-in variable of the HoA of storage default router.If router advertisement comprises ARA-Info (HoA of default router), then in step S41600, this address is stored in the above-mentioned built-in variable.
Below described modification to local fixed router 1100-1 behavior, the time carry out router advertisement being issued to its inlet.Fig. 9 has described this modification.In step S42000, localized immobilization router one 100-1 checks at first whether it has the previous HoA that stores of (knowing) its default router (being mobile access router one 200-1).If do not have this HoA, then with execution in step S42100, in step S42100, localized immobilization router one 100-1 will send does not have the router advertisement of ARA-Info.On the other hand, if it has the previous HoA that stores of its default router, then localized immobilization router one 100-1 will insert ARA-Info in the router advertisement of the HoA that comprises default router, as shown in step S42200.
As previously discussed, use the fourth embodiment of the present invention, or even exist under the situation of other router between mobile node and the mobile access router, mobile node also has the mechanism of the HoA of knowing upstream mobile access router.This allows mobile node that the access router option is embedded binding update messages, thereby allows the normal operation of ARO scheme.
